IPC: H03K17/687
Filed: 1988-08-05
Abstract: PURPOSE: To evade a degradation of a voltage in a high state by an excessive pull-down current by connecting a diode between a gate electrode and a source electrode of a transistor. CONSTITUTION: This circuit is composed of FETs T1 -T4 and a Schottky diode D1 .

The FET T4 is directly grounded through another switching device or through a [tail] transistor when the [tail] transistor is the part of a [long] tail pair]. Thus, when the gate current of the FET T1 is pulled to be low, switching is performed only to the state of passing through the current.
